2019-12-06gdb: fix overload resolution for see-through referencesTankut Baris Aktemur6-2/+29
The overload resolution mechanism assigns badness values to the necessary conversions to be made on types to pick a champion. A badness value consists of a "rank" that scores the conversion and a "subrank" to differentiate conversions of the same kind. An auxiliary function, 'sum_ranks', is used for adding two badness values. In all of its uses, except two, 'sum_ranks' is used for populating the subrank of a badness value. The two exceptions are in 'rank_one_type': ~~~ /* See through references, since we can almost make non-references references. */ if (TYPE_IS_REFERENCE (arg)) return (sum_ranks (rank_one_type (parm, TYPE_TARGET_TYPE (arg), NULL), REFERENCE_CONVERSION_BADNESS)); if (TYPE_IS_REFERENCE (parm)) return (sum_ranks (rank_one_type (TYPE_TARGET_TYPE (parm), arg, NULL), REFERENCE_CONVERSION_BADNESS)); ~~~ Here, the result of a recursive call is combined with REFERENCE_CONVERSION_BADNESS. This leads to the problem of over-punishment by combining two ranks. Consider this: void an_overloaded_function (const foo &); void an_overloaded_function (const foo &&); ... foo arg; an_overloaded_function(arg); When ranking 'an_overloaded_function (const foo &)', the badness values REFERENCE_CONVERSION_BADNESS and CV_CONVERSION_BADNESS are combined, whereas 'rank_one_type' assigns only the REFERENCE_CONVERSION_BADNESS value to 'an_overloaded_function (const foo &&)' (there is a different execution flow for that). This yields in GDB picking the latter function as the overload champion instead of the former. In fact, the 'rank_one_type' function should have given 'an_overloaded_function (const foo &)' the CV_CONVERSION_BADNESS value, with the see-through referencing increasing the subrank a little bit. This can be achieved by introducing a new badness value, REFERENCE_SEE_THROUGH_BADNESS, which bumps up the subrank only, and using it in the two "exceptional" cases of 'sum_ranks'. gdb/ChangeLog: 2019-12-06 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com> * gdbtypes.h: Define the REFERENCE_SEE_THROUGH_BADNESS value. * gdbtypes.c (rank_one_type): Use REFERENCE_SEE_THROUGH_BADNESS for ranking see-through reference cases. gdb/testsuite/ChangeLog: 2019-12-06 Tankut Baris Aktemur <tankut.baris.aktemur@intel.com> * gdb.cp/rvalue-ref-overload.cc: Add a case that involves both CV and reference conversion for overload resolution. * gdb.cp/rvalue-ref-overload.exp: Test it.

Origin of the leaks is in prune_inferiors: prune_inferiors is first removing the inferior to prune from the inferior list, then calls delete_inferior.

2019-12-04gdb/testsuite: Use -J option when compiling Fortran testsAndrew Burgess3-1/+18
When compiling Fortran tests (e.g. gdb.fortran/info-modules.exp), the Fotran compile produces .mod files. These files contain details of compiled modules that are then consumed by the compiler when compiling other files that USE a module. Currently the compiler writes the .mod files into its current directory, so for us this turns out to be 'build/gdb/testsuite/'. This means that .mod files can be shared between tests, which seems against the spirit of the GDB testsuite; source files should be compiled fresh for each test. This commit adds the -J option to the compiler flags whenever we compile a Fortran file, this option tells the compiler where to write, and look for, .mod files. After this commit there was one Fortran test that needed fixing, with that fix in place all of the Fortran tests pass again, but now the .mod files are now produced in the per-test output directories. gdb/testsuite/ChangeLog: * lib/gdb.exp (gdb_compile): Add -J compiler option when building Fortran tests. * gdb.mi/mi-fortran-modules.exp: Compile source files in correct order.

However, the thread list of the mock inferior set up in cooked_read_test is never initialized. So find_thread_ptid doesn't find the thread, which is an unexpected situation for inferior_thread. This is failing since this commit: 080363310650c93ad8e93018bcb6760ba5d32d1c Per-inferior thread list, thread ranges/iterators, down with ALL_THREADS, etc. Fix it by putting the mock thread in the thread list of the mock inferior in cooked_read_test. gdb/ChangeLog: * regcache.c (cooked_read_test): Initialize thread list of mock_inferior.

2019-12-04Compare iterators, not values, in filtered_iterator::operator{==,!=}Simon Marchi4-2/+176
The == and != operators on filtered_iterator are not doing the right thing, they compare values pointed by the wrapped iterators instead of comparing the iterators themselves. As a result, operator== will return true if the two iterators point to two equal values at different positions. operator!= will fail similarly. Also, this causes it to deference past-the-end iterators when doing. For example, in for (iter = ...; iter != end_iter; ++iter) the != comparison dereferences end_iter. I don't think this should happen. I don't think it's a problem today, given that we only use filtered_iterator to wrap linked lists of threads and inferiors. Dereferencing past-the-end iterators of these types is not fatal, it just returns NULL, which is not a value we otherwise find in the lists. But in other contexts, it could become problematic. I have added a simple self test that fails without the fix applied. gdb/ChangeLog: * filtered-iterator.h (filtered_iterator) <operator==, operator!=>: Compare wrapped iterators, not wrapped pointers. * Makefile.in (SUBDIR_UNITTESTS_SRCS): Add unittests/filtered_iterator-selftests.c. * unittests/filtered_iterator-selftests.c: New file.

2019-12-04Remove gdbarch_bits_big_endianTom Tromey13-55/+37
From what I can tell, set_gdbarch_bits_big_endian has never been used. That is, all architectures since its introduction have simply used the default, which is simply check the architecture's byte-endianness. Because this interferes with the scalar_storage_order code, this patch removes this gdbarch setting entirely. In some places, type_byte_order is used rather than the plain gdbarch. gdb/ChangeLog 2019-12-04 Tom Tromey <tromey@adacore.com> * ada-lang.c (decode_constrained_packed_array) (ada_value_assign, value_assign_to_component): Update. * dwarf2loc.c (rw_pieced_value, access_memory) (dwarf2_compile_expr_to_ax): Update. * dwarf2read.c (dwarf2_add_field): Update. * eval.c (evaluate_subexp_standard): Update. * gdbarch.c, gdbarch.h: Rebuild. * gdbarch.sh (bits_big_endian): Remove. * gdbtypes.h (union field_location): Update comment. * target-descriptions.c (make_gdb_type): Update. * valarith.c (value_bit_index): Update. * value.c (struct value) <bitpos>: Update comment.

2019-12-04Fix another build failure in tui-selftests.cTom Tromey2-1/+6
Christian had emailed me to say that the TUI unit test broke the mingw build, but I erroneously thought this was fixed by the earlier patch that made the test body conditional on the TUI being built. However, I was wrong about this -- tui-selftests.c unconditionally includes tui-winsource.h, which fails if curses is not available. This patch fixes the build problem by moving this include into the "#ifdef TUI" section. Tested by rebuilding a mingw-hosted gdb. gdb/ChangeLog 2019-12-04 Tom Tromey <tromey@adacore.com> * unittests/tui-selftests.c: Conditionally include tui-winsource.h.

2019-12-04gdb/mi: Add -max-results parameter to some -symbol-info-* commandsAndrew Burgess8-36/+180
Adds a new parameter -max-results to -symbol-info-functions, -symbol-info-variables, -symbol-info-types, and -symbol-info-modules. This parameter limits the number of results returned. This change still leaves -symbol-info-module-functions and -symbol-info-module-variables always returning all results, fixing these commands is slightly harder. There's currently no mechanism for the user of these commands to know if the result list has been truncated if you get back the maximum number of results, so if there are exactly 10 functions and you call '-symbol-info-functions --max-results 10' the reply would appear no different than if you had 20 functions and called with a max of 10. Right now, if you get back the maximum then you should assume that there might be more results available. One other thing to note is that the global_symbol_searcher::search by default returns SIZE_MAX results, there's no longer a mechanism to return an unlimited number of results, though hopefully this will not be a huge issue. gdb/ChangeLog: * mi/mi-symbol-cmds.c (mi_symbol_info): Take extra parameter, and add it into the search spec.

These return information about functions and variables within Fortran modules. gdb/ChangeLog: * mi/mi-cmds.c (mi_cmds): Add -symbol-info-module-functions and -symbol-info-module-variables entries. * mi/mi-cmds.h (mi_cmd_symbol_info_module_functions): Declare. (mi_cmd_symbol_info_module_variables): Declare. * mi/mi-symbol-cmds.c (module_symbol_search_iterator): New typedef. (output_module_symbols_in_single_module_and_file): New function. (output_module_symbols_in_single_module): New function. (mi_info_module_functions_or_variables): New function. (mi_cmd_symbol_info_module_functions): New function. (mi_cmd_symbol_info_module_variables): New function. * NEWS: Mention new MI command. gdb/doc/ChangeLog: * doc/gdb.texinfo (GDB/MI Symbol Query): Document new MI command -symbol-info-module-functions and -symbol-info-module-variables. gdb/testsuite/ChangeLog: * gdb.mi/mi-fortran-modules.exp: Add additional tests for -symbol-info-module-functions and -symbol-info-module-variables.

2019-12-04x86-64: accept 64-bit LFS/LGS/LSS forms with suffix or operand size specifierJan Beulich12-14/+101
Since we accept these without suffix / operand size specifier, we should also do so with one. (The fact that we unilaterally accept these, other than far branches, rather than limiting them to Intel64 mode, will be taken care of later on.) Also take the opportunity and make sure "lfs <reg>, tbyte ptr <mem>" et al get rejected outside of 64-bit mode. This became broken by dc2be329b950 ("i386: Only check suffix in instruction mnemonic"). Furthermore cover lgdt et al in the Intel syntax handling as well, which continued to work after said commit just by coincidence.
